Application of electrical submersible pumps in heavy crude oil in Boscan Field
- Maraven S.A., Lagunillas (Venezuela)
During recent years optimization of artificial lift methods has been applied in the oil industry, in order to evaluate the effect on oil well production and to establish a company`s optimal investment policies. Higher costs on new artificial lifting equipment and facilities for new fields have created the necessity to review the latest available technology of different lifting methods and specially that related to electrical submersible pumps (ESP). Few studies in the area of heavy crude oil production optimization using ESP as a lifting method have been published. This paper discusses the results of an ESP pilot project performed in 24 wells in Boscan field, and analyzes the performance of the equipment and its application range. The ESP equipment was installed in completions at depths ranging from 7000 to 9000 feet, with a 10{degrees}API gravity crude and bottomhole temperature of 180{degrees}F. It was concluded that despite a reduction of the pump`s efficiency, the ESP equipment does qualify as a good alternative lifting method for heavy oil production. It is also possible to obtain higher production rates. The results obtained in this pilot project, confirm that submersible pumps are an alternative method for lifting heavy crude oil from relatively deep reservoirs.
